Food grade is a paperwork product

The uncomfortable framing

Customers occasionally push back on food grade pricing on the grounds that the container does not look any better. They are correct. It frequently does not look any better, and sometimes it looks worse — a single-trip corn syrup container can carry more staining than a three-trip detergent container that has been through a caustic wash.

What you are buying is a documented, verifiable answer to four questions, and the reason it costs more is that the supply of containers with defensible answers is small and the demand is not.

The four questions

1. What was in it before, specifically? Not a category — a product name and a shipper. "Food product" is not an answer and an auditor will not accept it.
2. How many times has it been filled? Food grade means once. A container on its third fill is a reconditioned container with an optimistic label.
3. What was it washed with, and was the wash water potable? Municipal potable feed, hot, food-grade sanitiser at label concentration, with the record to show it.
4. What was replaced? Gaskets and valve elastomers are porous, absorbent and impossible to verify. On a food unit they are new, not cleaned.

Every one of those is a records question. None of them can be answered by looking at the container, which is precisely why the premium is invisible.

What the document actually says

Our prior-contents declaration is one page on letterhead, signed by the yard supervisor, and it names: the lot number, the unit numbers it covers, the prior product, the shipper, the fill count, the wash level applied with date and operator, the components replaced, and the grade assigned. It does not say "food grade certified", because there is no certifying body and any supplier using that phrase should be asked which one.

Where the supply comes from

Understanding the supply side explains the price. Food grade containers come from a narrow set of sources, all of which are receivers of bulk edible liquids: beverage plants taking high-fructose corn syrup or juice concentrate, food manufacturers taking glycerin or edible oils, pickling and sauce operations taking vinegar.

Every one of those is a single-trip container from a receiver who does not refill. That is a small pool, it does not grow when demand rises, and it is why food grade availability in a specific size and quantity can genuinely require a week or two of notice. When we say we need lead time on a food grade order, that is why.

The cheaper answer nobody asks about

If what you need is a clean interior with no prior-contents question, and the audit trail on the cage is not something your programme cares about, a rebottled container gives you a virgin never-filled bottle for typically less than a food grade unit and with no availability constraint at all.

Roughly a third of the customers who come to us asking for food grade leave having bought rebottled, because their actual requirement was a clean interior rather than a documented history. It is worth being precise about which one you need — they cost different amounts and they solve different problems.
